Abstract
PURPOSE:To execute voice recording and reproducing with high tone quality and to execute digital dubbing by compressing data, adding a high-efficient error correcting code to the data, and high-densely recording the frame-composed data on a limited area by using code modulation. CONSTITUTION:A standardized digital signal inputted from an input terminal 2 is inputted to a compressing symbol generating circuit 5. Thereafter, when a quasi-instantaneous compression is given, range information previously determined at a range information detecting circuit 4 is detected, its output is inputted to a control signal generating circuit 6 and added to a control signal. Further, the digital signal, to which the quasi-instantaneous compression is given from a terminal 3, is dispersed by an interleaving circuit 8. Thereafter, the error correcting signal to correct an error, which occurs at the time of regeneration, is added to the data by an error correcting circuit 9 after a frame with low redundancy is composed. Thereafter, the frame-composed data are high- densely recorded on the limited area by using the code modulation.
